OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Project 2: Cash Register
Part 1:
Write a class named RetailItem that holds data about an item in a retail store. The class should store the following data in attributes: item description, units in inventory, and price. Once you have written the class, write a program that creates three RetailItem objects and stores the following data in them:
Description. Units in Inventory Price
Item #1 Jacket 12 59.95
Item #2 Designer Jeans 40 34.95
Item #3 Shirt 20 24.95
Part 2:
Create a CashRegister class that can be used with the RetailItem class. The CashRegister class should be able to internally keep a list of RetailItem objects. The class should have the following methods:
• A method named purchase_item that accepts a RetailItem object as an argument. Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list.
• A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list.
• A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list.
• A method named clear that should clear the CashRegister object’s internal list.Demonstrate the CashRegister class in a program that allows the user to select several items for purchase. When the user is ready to check out, the program should display a list of all the items he or she has selected for purchase, as well as the total price.
